    摘要： A completion and workover fluid composition comprising, water and at least one rheology modifier and/or fluid loss control agent, and at least one other ingredient selected from the group consisting of inorganic salts, shale inhibitors, corrosion inhibitor, biocide, defoamers and finely divided solids particles (e.g., bentonite, attapulgite, sepiolite, calcium carbonate, etc.), depending upon the desired attributes, wherein the rheology modifier and/or the fluid loss control agent is an ethoxylated raw cotton linters or a modified ethoxylated raw cotton linters. The ethoxylated raw cotton linters provides comparable or better rheology and viscosity properties compared to high molecular weight commercial HECs made from purified cotton linters. These ethoxylated raw cotton linters derivatives are suitable for applications in oil-well servicing fluids, particularly to enhance functional properties of completion and workover fluids used during oil-well drilling operations.

    摘要： An oilfield servicing fluid composition containing an aldehyde guar produced by enzymatic oxidation of a non-derivatized, straight guar or of a guar derivative. The enzyme used to oxidize the guar to the aldehyde guar is galactose oxidase, which may be combined with catalase or catalase and peroxidase. The aldehyde guar is useful as an effective gelling agent for oilfield servicing fluids such as hydraulic fracturing fluids and stimulation fluids.
